“I eat a little bit of everything and not a lot of anything,” said De Laurentiis. “Everything in moderation.”

The curvy but lean Giada said the No. 1 question fans ask her is what her diet secret is. De Laurentiis, 44, said what works for her is to never overeat.

“I know that’s really hard for people to understand, but I grew up in an Italian family where we didn’t overdo anything,”she said. “We ate pasta, yes, but not a lot of it. Pasta doesn’t make you fat. How much pasta you eat makes you fat.”

De Laurentiis, author of the cookbook Giada at Home, also makes a point to eat healthy foods, filling up on kale, brown rice, and olive oil instead of junky processed foods. She also exercises every day, doing yoga, hiking, and Pilates workouts.

“Morning workouts, every day, are the best thing for me,” said Giada, who has a six-year-old daughter, Jade, with husband Todd Thompson.

“I do yoga, which I got into while I was pregnant, or a half hour on the elliptical and 20 minutes on the treadmill. Getting up and getting my blood going gives me energy for the whole day.

Interestingly, De Laurentiis said she got in better shape after scaling back on rigorous cardio workouts, which she did obsessively during her twenties and thirties.

“I was a big gym rat for a long time — treadmill, elliptical machine, StairMaster, weights,” she said. “But I started doing yoga and paddle-boarding, which is peaceful, almost like a meditation. And I go hiking.”
